Question
Hi, I need a free, downloadable viewer for STP & IGS files. I do not have any kind of CAD software installed on my PC. I only need to be able to look at these drawings, not make any changes, markups, print or email. I have tried several viewers which claim to be able to work with these file types, but so far none have and I can't even get to talk to a live human being from the companies who post them on their websites. HELP !!!!!!!

Answer
Hey Dave, i've used Myriad before (purchased) opening both formats but i think you'd be able to open STL files w/ the free version. As far as the IGES format, i'm not sure if there's anything available for free.
However, if you run out of options, you can always check out Alibre Design express. Hope this helps!
